Abstract: PROBLEM TO BE SOLVED: To make an optimization of, and improve an efficiency of a time-out error detection and a process time for a serial printer(SP) apparatus by making setting of a time-out timer variable according to the type of a command transmitted to the SP printer apparatus. SOLUTION: A command of a print and the like is transmitted from a central process apparatus to an SP apparatus (S001). When a data transmitted is an image data, a time-out(TO) time is set relatively short according to a print capability (S004).
